Societal responses to the Anthropocene - published in the Theme Issue of the Philosophical Transaction of the Royal Society, 13 March 2011: "The Anthropocene: a new epoch of geological time?". "The idea that humans could so transform the land surface, seas and atmosphere of the Earth to establish a new geological epoch in their own name is startling in itself, and would have amazed earlier generations. Yet, since the beginning of the industrial revolution some 250 years ago, humans have profoundly affected the Earth and all life on it. The consequences are becoming more evident every day, but in the longer term remain almost unknowable ... "

Carbon trading and cash values on forests cannot curb carbon emissions - Oscar Reyes argues that climate change solutions cannot be created by unfettered markets, despite what business leaders think, The Guardian, Thursday 28 May 2009. "When Sir Crispin Tickell had the temerity to suggest that 'the business community needs to re-examine the fundamentals of economics' at the recent World Business Summit on Climate Change in Copenhagen, his discordant tone was drowned out by a chorus of more than 800 delegates singing the praises of unfettered markets as a means to tackle climate change ...

Climate change - the hazards - Lecture at the University of Sheffield, 13 February 2007. "Perhaps the point that still escapes many people is the limited, ephemeral and precarious character of the global environment. Our whole being is within a wafer-thin atmosphere surrounding the surface of a planet as it turns in space at exactly the right distance from the Sun for life. We are tiny parts of a system of life whose complexity passes, and always will pass, human understanding ... "
Climate change: implications for security - A lecture to the Royal United Services Institute for Defence & Security Studies (RUSI) Conference on "Climate Change: The Global Security Impact". At RUSI, Whitehall, London; 24 January 2007. "Fears about climatic, change have replaced the equally apocalyptic fears of nuclear annihilation during the Cold War. It is therefore no wonder that military authorities have taken more interest in it than others who find it hard to come to grips with its complex implications. Yet not many governments have so far taken seriously the papers written by such people as the Pentagon or the British Ministry of Defence, and incorporated into their strategic planning ... ".
Gaia and the human impact: Earth system science - Lecture to the Annual Conference of The Association for Science Education, University of Birmingham, 4 January 2007. "Change rarely proceeds in curves. It goes in steps and thresholds. Due perhaps to the shortness of our individual lives and our lack of imagination we tend to believe that what we know - the current diversity of life and the climate around us - will only change within narrow limits; and that if nature is allowed to take its course, things will revert to where they were. Unfortunately history gives no foundation for this belief ... "

Climate change and the variety of life - a lecture delivered at the Botanical Gardens, Edinburgh, 14 April 2004, as part of the Edinburgh Science Festival. "the price of sticking to our present system of values and not adapting to new ones is intolerably high. So far all past urban civilizations - some 30 of them - have crashed. None over time learned how to reach a well-regulated steady state with population in balance with natural resources. There is no reason to believe that ours is any different. Indeed current signs are to the contrary ... ".
The impact of climate change on the economy - speech to the Woodhouse Group, University of Leeds, 10 February 2004. "It is notoriously difficult to distinguish natural from man made processes, but there is a growing consensus, expressed in successive reports from the Intergovernmental Panel on Climate Change, that the human contribution is now having a significant if not decisive effect."

Climate change and the Kyoto Protocol - Notes for a talk at Harvard University. "I remember that before the Rio Summit of 1992 George Bush senior tried to reassure the American people by saying that no-one was going to change the American way of life. He was dead wrong. North Americans must change their way of life, as we in Europe must change ours. Otherwise Nature will do what she has done to over 99% of species that have ever lived, and do the job for us."
Communicating Climate Change - Published in Science Volume 297, Number 5582, Issue of 2 Aug 2002. " I remember the editor of a leading British broadsheet dismissing climate change as yesterday's story. News has to have a beginning and an end, and often has to be artificially polarized. A process that occurs over years or centuries is hard to report on very often. Moreover, the story carries uncomfortable implications... "

Risks of conflict - resource and population pressures - Linacre Lecture, University of Oxford. "Looking ahead at the prospects for conflict, we seem to be in for a bumpy ride. Violence within and between communities and between nation states could well increase. The precedents are all around us. It would be naïve to expect otherwise, and we must be prepared for it..."
Something new under the sun - review of Something New Under the Sun - An Environmental History of the Twentieth Century, by John McNeill. "For once there is something new under the sun. Up to now there has been a precedent for most things: population explosions of particular plants or animals; periodical extinctions; changes in soil fertility; rapid global cooling and rapid global warming; even impacts of objects from outer space. But in the history of life ... there has been nothing like the impact of one animal species - our own - on the condition of the earth, and most of it within a single century ... "
Science, public policy and climate change - Interview with Sir Crispin Tickell by Barbara Geary of Rolex. "If the US persists in being the world's biggest polluter, then the rest of the world will have to consider introducing measures such as taxing US exports to compensate for the lack of a national emissions tax in the United States. "
Visions of the 21st Century - a view to the future at the turn of the Millennium. "In so far as we can peer a hundred years ahead, we can wish our successors well, and hope that they will enjoy more of an equilibrium than is possible in our own unsustainable and crowded but creative society... I suspect that they will look back on us as a messy, short-sighted, wasteful, crude, and aggressive lot. Let us hope they are not the same."
El Nino and its significance - An evening discourse at the Royal Institution, London. "In this lecture I want to bring out the smallness and variable conditions in our living space and the enormous effects which even relatively minor and temporary changes can make in it. I want to look not only at the history and science of the El Nino phenomenon, but also at climate change in general and the vulnerability of all species, including our own, to such change, the more so at a time when human activity is seen to be accelerating it..."
